  ----------------------------------------------------------
   This  case  concerns  axisymmetric incompressible laminar
   (or  turbulent  LTURB=  T)  flow  in the pipe with linear
   expansion.   The  flow  exhibits  recirculation  in   the
   region on  the pipe  axis. That  kind of  flows is common
   for gas burners.

   The problem is  set in Y-Z  plane; the swirling  velocity
   component UC1 is solved as scalar using special treatment
   (LSG6= T). User can model the same problem as 3D  (NX>1),
   however the speed of convergence, provided the problem is
   truly axisymmetric, is rather slow.

   User can switch from the default colocated  computational
   algorithm (CCM)  to the  staggered one  (STAG) by setting
   LCCM= F.
